g++-10.0.1-alpha20200412 snapshot (g:87be4cecfc6e42390303be1ca92bc8bc587b0bd6)
and g++ 9.3 both don't crash, rejecting it instead:
% g++-10.0.1 -c pr91538.C
pr91538.C: In function 'void f()':
pr91538.C:3:8: error: no match for call to '(f()::<lambda(auto:1 ..., decltype
(args)...)>) (int)'
3 | l(0);
| ^
pr91538.C:2:14: note: candidate: 'f()::<lambda(auto:1 ..., decltype (args)...)>
[with auto:1 = {}]'
2 | auto l = [](auto... args, decltype(args)...){};
| ^
pr91538.C:2:14: note: candidate expects 0 arguments, 1 provided
as do clang++ 9 and 10:
% clang++-10 -c pr91538.C
pr91538.C:3:5: error: no matching function for call to object of type '(lambda
at pr91538.C:2:14)'
l(0);
^
pr91538.C:2:14: note: candidate function [with args:auto = <>] not viable:
requires 0 arguments, but 1 was provided
auto l = [](auto... args, decltype(args)...){};
^
1 error generated.
So it looks like this PR is really ice-on-invalid-code for gcc 8?
